The Oklahoma-style smash burger is a twist on the traditional Oklahoma burger where meat patties are placed on top of and pressed onto raw onion rings to fuse the two together. Here, for our Make Your Own Epic Burger Adventure, we pressed caramelized onions on top of a half-cooked burger for a sweeter, fancier taste.
In a large sauté pan, heat the butter over high heat. Add the onions and cook, stirring occasionally, for about 15 minutes, until browned. Season with salt and pepper. Set aside and keep warm. Meanwhile, lay the cheese slices on the bottom half of the 4 baguette slices and toast in a toaster oven or a broiler until the cheese is melted, keep warm.
Cook the Butter-Basted Burgers in the same manner, but after flipping the burgers, add the cooked onions to each patty and press down with a spatula.
Place the burgers on each of the remaining baguette halves, top with the onions and the melted cheese and bread slice. Enjoy!
